BACKGROUND
BACKGROUND
[0003] New environmental regulations on refrigerants have forced the refrigeration and air-conditioning industry to look for new refrigerants with low global warming potential (GWP).
[0004] Replacement refrigerants are being sought that have low GWP, low toxicity, low or non-flammability, reasonable cost and excellent refrigeration performance. Fluoroolefins provide satisfy these criteria. In addition, desired properties in a refrigerant include ease of detecting leaks, performance including efficiency and capacity refrigerant applications, solubility in lubricants used in such applications and compatibility with components used in such applications.
[0005] 2,3,3,3-Tetrafluoropropene (HF0-1234yf, R-1234yf, or 1234yf) is an example of a fluoroolefin having a low Global Warming Potential (GWP) and is an alternative to high GWP hydrofluorocarbons and/or ozone-depleting hydrochlorofluorocarbons in numerous applications such as refrigeration, air-conditioning, heating and cooling, power cycles.
Improvement in properties of compositions comprising 1234yf is desired.
